FIELD OF INVENTION

This invention relates to a sleeping system with multiple firmness configurations.

BACKGROUND OF THE INVENTION

There are a variety of reasons that would lead a person to want to alter the firmness of his or her bed. When a person experiences a change in condition such that an alternate bed firmness is desired, conventional beds offer no opportunity for such a change. Conventional beds include a box spring with a mattress on top. As is generally known, mattresses are available for purchase in a variety of firmness levels. Accordingly, a purchaser may select a bed which is appropriate at that point in time. Unfortunately, as the bed ages and as the user experiences life changes, the comfort and firmness of the bed may not meet the needs of the user. Generally, the process of selecting a conventional bed consists of briefly lying on a display bed in a retail store. Such brevity in a retail setting is likely not sufficient to properly identify the desired bed firmness. Further, when a consumer buys a conventional bed, it is then his or hers, without an opportunity for exchange or upgrade. It is well know that conventional beds do not provide for adjustment of the bed's firmness. So, as the bed ages or the user desires a change, the only available option is to purchase a whole new bed.

SUMMARY OF INVENTION

Disclosed herein is a sleeping system that provides at least six different firmness levels per bed, which may adjusted by an end user. As further described herein, the present invention may be reconfigured in a variety of ways in order to provide a user the convenience of an altered firmness level with little effort. Also disclosed herein is a method of selling the sleeping system by using minimal retail floor space. Also disclosed is a method of exchanging the comfort layer of the sleeping system after it has been sold in order to provide the user with further alternate firmness levels. That is, the invention disclosed herein provides the benefit of a single sleeping system having modular components so that, after it is sold, the comfort layer may be easily exchanged for a new or alternate comfort layer which is compatible with the sleeping system. The sleeping system includes a comfort layer, support layer, and foundation layer. For each layer, different types of technology, such as latex or foam, may be chosen to customize the resulting sleep experience.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

In one exemplary embodiment, the present invention is a sleeping system that is easily adjustable to different levels of firmness. The sleeping system, referred to as the system 10, includes a comfort layer 12, support layer 14, and a foundation layer 16. A retailer, wholesaler, or end user may position or reconfigure the three layers in order to customize the sleeping surface. Specifically, the comfort layer 12 is sized for easy rotation, flipping, or removal, as desired. The resulting adjustments to the firmness of the system 10 are further discussed below. Further, the present invention includes a method of selling the system 10 in which only minimal floor space is required for display. Further, the methods disclosed herein allow for selling the systems 10 at various price points depending upon the desire of the consumer. Finally, the methods disclosed herein allow for the exchange, or replacement, of the comfort layer 12 of the system 10 after the system 10 has been sold so that the end user may experience yet an alternate level of firmness.

Referring now to FIG. 1, there is shown an isometric view of the system 10 including a comfort layer 12 positioned on top of a support layer 14, which is positioned on top of a foundation layer 16. In certain embodiments the system 10 may be positioned on a bed frame 18, or other mount, as known to those of ordinary skill in the art. Customization of the system 10 is accomplished by rotating, flipping, or removing the comfort layer 12. Further customization is accomplished by rotation of the foundation layer 16. In certain embodiments of the present invention, the comfort layer 12 and the foundation layer 16 each have multiple firmness sections therein. The line of delineation between the two firmness sections may be along the longitudinal middle of each layer, as best seen in FIGS. 2-5B. In alternate embodiments, the boundary of such firmness sections may be according to the needs of a user, as further described in the next paragraph. By orienting or configuring the firmness sections of the comfort layer 12 and foundation layer 16, the retailer or end user is altering the firmness of each sleeping position of the system 10. While the figures represent systems 10 sufficient for sleeping two people, in other embodiments, the system 10 may be constructed for a single person.

Referring now to FIG. 2, there is shown a top view of a comfort layer 12. Shown therein is the first firmness section 20 and second firmness section 22 of the comfort layer 12. The broken line therein is a schematic delineation of the boundaries of the two firmness sections. In the embodiment shown, the first firmness section 20 is firm and the second firmness section 22 is plush, or soft. In alternate embodiments of the comfort layer 12, or the foundation layer 16, the boundaries of the firmness sections may change depending upon the needs of the end user. For example, in certain embodiments, firmness sections may have horizontal boundaries, rather than longitudinal boundaries, in order to create comfort zones for better posture. By way of example, a comfort layer 12 or a foundation layer 16 may have different firmness sections corresponding to different areas of the body, such as the torso or legs. By way of another example, a comfort layer 12, or a foundation layer 16, may have a section therein which is firm and another section therein which is plush, soft or less firm. As further described herein, the comfort layer 12 may be rotated for firmness and flipped for longevity.

Shown in FIGS. 3, 4, 5A and 5B are cross sectional views of alternate configurations of the three layers within the system. The cross-sections, or slices, which result in the views shown in FIGS. 3 and 4 are along the 3-3 and 4-4 lines shown in FIG. 7. The cross-section which results in the views shown in FIGS. 5A and 5B are along the 5A-5A line and 5B-5B line, respectively, shown in FIG. 6. The hatching shown in FIGS. 3-5B represents various materials of construction, which are described in detail below. The purpose of the hatching is to show that each firmness section is constructed of a different material. Thus, resulting in the different firmness levels. As further described herein, reorienting or reconfiguring the comfort layer 12 and the foundation layer 16 results in at least six different firmness levels. Those firmness levels are shown in the hexagon shapes in the Figures and are referred to as firmness levels 1-6, with firmness level one being the most firm and firmness level 6 being the most plush. Stated another way, beneath each hexagon shape is a portion of the system 10 including a foundation layer 16, support layer 14 and comfort layer 12 which result in the firmness level indicated. As further described below, firmness levels 1 and 2 result from a foundation layer 16 and support layer 14, without a comfort layer 12. Accordingly, a single system 10, having a foundation layer 16, support layer 14, and comfort layer 12 may be oriented or configured to provide the six firmness levels described herein. Even more alternate firmness levels may be accomplished by substituting into a system 10 a layer made of different materials of construction than the layer which it replaces.

Referring now to FIG. 3, there is shown a cross sectional view of the system 10. Regarding the comfort layer 12, the first firmness section 20 is firm. The second firmness section 22 of the comfort layer 12 is plush, or soft. The support layer 14 has a consistent firmness such that multiple levels of firmness are not available within the support layer 14. With reference to the foundation layer 16, the first firmness section 24 is firm and the second firmness section 26 is plush. As known to one of ordinary skill in the art, the relative firmness of the comfort layer 12 and the foundation layer 16 differ due to the function of each within the system 10. Discussion of materials of construction of each layer is provided below. In the orientation shown in FIG. 3, firmness level six, the most plush, or soft, is achieved by the combination of the second firmness section 22 of the comfort layer 12, the support layer 14, and the second firmness section 26 of the foundation layer 16. Also shown in FIG. 3 is the resulting firmness level three, due to the combination of the first firmness section 20 of the comfort layer and the first firmness section 24 of the foundation layer 16, both of which are firm. In still other embodiments of the present invention, the first firmness section 24 and the second firmness section 26 of the foundation layer 16 may result from the use of separate foundation units which are placed side by side on a bed frame, as further described in relation to FIG. 5B. In such a configuration, the ability to adjust firmness is still present.

Referring now to FIG. 4, there is shown a cross sectional view of the system 10, which has been reconfigured by rotating or flipping the comfort layer 12. As compared to FIG. 3, the orientation of the comfort layer 12 has been changed such that the location of the first firmness section 20 of the comfort layer 12 has been reversed with the second firmness section 22 of the comfort layer 12. Firmness level four results from the combination of the first firmness section 24 of the foundation layer 16 and the second firmness section 22 of the comfort layer 12. Also shown is resulting firmness level five, due to the combination of the second firmness section 26 of the foundation layer 16 and the first firmness section 20 of the comfort layer 12.

Referring now to FIG. 5A, there is shown an embodiment of the system 10 having a foundation layer 16 having two firmness sections. In an alternate embodiment shown in FIG. 5B is a system 10 having two separate foundation layers 16, each having a different firmness, being placed side by side. Each embodiment shown includes the support layer 14. The comfort layer 12 has been removed from each embodiment of the system 10. In the embodiment shown in FIG. 5A, firmness level one, the most firm level, results from the support layer 14 in combination with the first firmness section 24 of the foundation layer 16. Firmness level two results from the combination of the support layer 14 and the second firmness section 26 of the foundation layer 16. In the embodiment shown in FIG. 5B, firmness level one, the most firm level, results from the support layer 14 in combination with the first foundation layer 16 providing firmness section 24. Firmness level two results from the combination of the support layer 14 and the second foundation layer 16 providing firmness section 26.

Referring now to FIG. 6, there is shown an embodiment of the present invention in which the comfort layer 12 has been removed from the system 10. The support layer 14 has a first side 32. The first side 32 of the support layer 14 is constructed of upholstered material such that a sleeping surface is provided. Accordingly, when the comfort layer 12 is removed from the system 10, the first side 32 is exposed and may be used as a comfortable sleeping surface.

Referring now to FIG. 7, there is shown the system 10 in which the comfort layer 12 is bent upward away from the support layer 14 in order to show its flexibility and the first side 28 and the second side 30. The comfort layer 12 is constructed so that both the first side 28 and the second side 30 are sleeping surfaces. To be clear, the comfort layer 12 may be flipped, or rotated, such that either the first side 28 or the second side 30 is facing upward and used for sleeping.

Each of the comfort layer 12, support layer 14, or foundation layer 16 may be selected from a plurality of available firmnesses or mixture of firmnesses. Any of the following examples of each layer may be positioned so that the support layer 14 is on top of the foundation layer 16 and the comfort layer 12 is on top of the support layer 14, in order to provide a system 10, as described herein. In certain embodiments, the system 10 may have the dimensions as known to those of ordinary skill in the art, for example, a single bed, double, queen, king, and the like. In certain embodiments of the present invention, the foundation layer 16 and comfort layer 12 may not have multiple firmness sections on the longitudinal halves of the system 10 for twin size systems 10, although alternate firmness section positioning, as described above, may apply. That is, in a narrow twin size unit, having multiple firmness sections as shown in FIG. 2 may not be desirable.

Regarding the invention disclosed herein, each system 10 includes only one of each layer, and the composition of each layer may be selected from abundant choices. Disclosed below are exemplary materials of construction and embodiments of the present invention. Such disclosure allows one of ordinary skill in the art to make the present invention. In certain embodiments of the present invention, the foundation layer 16 may be constructed of material well known to those of ordinary skill in the art, including, wood, steel wire grids, steel coils, polyurethane foam, or the like, and/or any combination thereof. In certain embodiments of the present invention, the foundation layer 16 may consist of two separate units which are placed side by side, as best seen in FIG. 5B. Accordingly, each foundation layer 16 unit is constructed of certain materials in order to provide a certain firmness. In such an embodiment, each foundation layer 16 unit acts like a either a first firmness section 24 or a second firmness section 26. In still other embodiments of the present invention, as best seen in FIG. 5A, the foundation layer 16 may be constructed as a single unit having a first firmness section 24 and a second firmness section 26. By way of example, in a certain embodiment, a foundation layer 16 may have a first firmness section 24 that is constructed of wood and a second firmness section 26 that is constructed of wood and a steel wire grid. In another embodiment, the foundation layer 16 may, for example, have a first firmness section 24 that is constructed of steel coil springs and a second firmness section 26 that is constructed of wood, a steel wire grid, and padding. Many combinations of materials known to those of ordinary skill in the art may be used. To be clear, any of the materials of construction may be mixed and matched to obtain a foundation layer 16 having a firmness section, or multiple firmness sections, so that each firmness section has the specifically desired firmness. The foundation layer 16 is then encased within an upholstered covering as known to those of ordinary skill in the art. Those of ordinary skill in the art are familiar with the manner of gluing, sewing, or otherwise attaching the various materials in order to construct a unitary foundation layer 16. Those of ordinary skill in the art are also familiar with the manner of constructing each of the various layers of the system 10 disclosed herein. By way of background, U.S. Patents and U.S. Patent application Publications for various beds include U.S. Patent Application Publication No. 2007/0283501 A1 published on Dec. 13, 2007 by Mossbeck; U.S. Pat.

As stated herein, the materials of construction described are readily commercially available and well known in the bedding industry. Also, manufacturers are readily available for the manufacture of such bedding goods, according to the known methods of manufacture within the bedding industry.

In certain embodiments of the present invention, the foundation layer 16 may have a height of from about 4 inches to about 12 inches, and is preferably 8-10 inches high. The foundation layer 16 is not intended to provide a sleeping surface. Accordingly, such additional padding or preferred fabric associated with a sleeping surface is not present. While only limited examples of the construction of the foundation layer 16 have been described herein, those of ordinary skill in the art will appreciate the large number of differing adjustments which may be made to the disclosure provided herein.

In certain embodiments of the present invention, the support layer 14 may be constructed of material similar to those used in a conventional mattress. Such materials generally including steel inner springs, polyurethane foam, wool, cotton, latex foam, memory foam, and the like, and/or any combination thereof. In certain embodiments, the support layer 14 may include air chambers, bladders, or the like. Such materials are well known in the bedding industry and readily commercially available. The support layer 14 has a consistent firmness, or density, and does not have various firmness sections like the foundation layer 16 and the comfort layer 12. The support layer 14 is encased within fabric or other conventional material as known in the bedding industry. The first side 32 of the support layer 14 is provided to be a sleeping surface. Accordingly, the first side 32 is covered in an upholstered material, as known to those of ordinary skill in the art, in order to provide a comfortable sleeping surface. Such upholstered materials are readily commercially available and well known in the bedding industry. Such materials are fixedly secured, as known to those of ordinary skill in the art, to the support layer 14. In certain embodiments of the present invention, the support layer 14 has a height of from about 9 inches to about 16 inches. In still other embodiments, the support layer 14 has a height of from about 9 inches to about 12 inches.

In certain embodiments of the present invention, the comfort layer 12 may be constructed of material well known in the bedding industry and readily commercially available, such as gel, latex foam, memory foam, micro-coils, polyurethane foam, and the like, and/or any combination thereof. In certain embodiments of the present invention, the comfort layer 12 may, for example, have a first firmness section 20 constructed of memory foam and a second firmness section 22 constructed of latex. In other embodiments, the comfort layer 12 may, for example, have a first firmness section 20 constructed of latex foam and a second firmness section 22 constructed of a mixture of latex foam and memory foam. In still other embodiments, the comfort layer 12 may, for example, have a first firmness section 20 constructed of gel and a second firmness section 22 constructed of latex foam. To be clear, any of the materials of construction may be mixed and matched to obtain a comfort layer 12 having a firmness section, or multiple firmness sections, so that each firmness section has the specifically desired firmness. Those of ordinary skill in the art are familiar with gluing, sewing, or otherwise fixedly securing the first firmness section 20 to the second firmness section 22 of the comfort layer 12. Both the first side 28 and the second side 30 of the comfort layer 12 are covered with an upholstered material, or other sleeping surface fabric, so that a user may sleep on either side. As previously stated herein, such materials are readily commercially available and well known in the bedding industry. In certain embodiments of the present invention, the comfort layer 12 may have a height of from about 3 inches to about 7 inches. In alternate embodiments, the comfort layer 12 may have a height of from about 4 inches to about 6 inches.

The sleeping system 10 is easily reconfigured by a person. One manner of reconfiguring the system 10 is to remove the comfort layer 12. Another manner of reconfiguring the system 10 is to rotate, or flip, the comfort layer 12, in order to reverse the positions of the firmness sections therein. Also, a person may rotate (not flip) the foundation layer 16. That said, in practical terms, rotating the foundation layer 16 is really just repositioning the system 10 so that the head of the bed is swapped with the foot of the bed. In alternate embodiments having side by side foundation layer 16 units, a person may reverse the positioning of the side by side foundation layer 16 units. The wide range of adjustable bedding which is provided by the present invention has been described herein. Any of the many foundation layers 16 may be combined with any of the many comfort layers 12 in order to build a bed which provides the desired firmness. Additionally, in certain embodiments, varieties of materials of construction for the support layer 14 allow for selection of a support layer 14 to compliment the foundation layer 16 and comfort layer 12.

The method of selling the present system 10 provides the benefit that only a limited number of display systems 10 are needed on retail floor space, rather than a large number of individual beds, each of which offers a different firmness. Because the comfort layer 12 may be easily rotated, flipped, or removed by a single person, all six of the firmness levels of a system 10 may be shown to, and experienced by, a consumer with the use of only a single display system 10. Further, many comfort layers 12 having alternate firmnesses may be stored near the system 10 for easy substitution with the system 10. The only reason there would be a need for multiple display systems 10 would be display alternate foundation layers 16. Given the larger size of the foundation layer 16, and the necessity to remove the support layer 14 therefrom, it may be less practical for a retailer to provide such reconfiguration while attempting to make a sale. Requiring drastically less retail floor space while still offering the opportunity to test multiple firmness levels is a benefit to the retailer such that the store size may be smaller. Alternatively, a retailer may use the remaining floor space to display other goods for sale.

The current system 10 also provides the opportunity to offer different price points of bedding depending on the configuration of the system 10 sold. In certain embodiments of the present intention, a retailer may offer a system 10 at a reduced price point merely by not including the comfort layer 12 in the sale. In alternate embodiments, the retailer may offer bedding at a higher price point by including the comfort layer 12.

After selling the present system 10, continued alteration of the firmness of the sleeping system 10 may be provided by exchanging the comfort layer 12. In certain embodiments of the present invention, a retailer, or wholesaler, that sold a system 10 may exchange, or replace, the comfort layer 12 of the system 10 without having to replace the remainder of the system 10. In the bedding industry, when a bed is sold, it is the property of the consumer without the opportunity for exchange of any of the parts thereof. In the present invention, the party selling the system 10, generally a retailer or wholesaler, may exchange the comfort layer 12 by mail, or shipping. Those of ordinary skill in the art are familiar with the many types of mailing or shipping which would be appropriate to provide timely transport of comfort layers 12 as described herein. For example, at a point in the future, a retailer may provide a previous consumer an alternate firmness experience by providing the latest comfort layer 12 for use in combination with the consumer's system 10, which may have been purchased years before. This method of exchanging component parts may be applied to other bedding as well.

This patent application expressly incorporates by reference all patents, references, and publications disclosed herein.
